HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Andrew [12]
Answer:  x = 9.611 ;  or ;  x = 9  11/18 .
_________________________________________________
Explanation:
________________________________________________

All angles of any triangle must add up to 180 degrees.

So,  (10x - 4)  + (8x + 3) + 91 = 180 ;  Solve for "x" ; 
___________________________________________
    10x - 4 + 8x + 3 + 81 = 180 ;

Combine the "like terms" on the left-hand side of the equation:
___________________________________________
      +10x + 8x = 18x ;
        
       - 4 + 3 + 8 = 7 ;
____________________________
          18x  +  7 = 180 ;
___________________________________________
   Subtract  "7" from each side of the equation:
___________________________________________
         18x + 7 - 7 = 180 - 7 ;
___________________________________________
to get:  
  
         18x  = 173 ; 
_________________________________
Divide EACH side of the equation by "18" ; to isolate "x" on one side of the equation;  and to solve for "x" ; 
_________________________________
         18x / 18  = 173 / 18 ;
_________________________________
                   x = 9.6111111111111111....
_____________________________________
  
Write as:  9.611 ;  or;   9  11/18.

If y varies inversely as x, and y = 10 when x = 20,<br> find x when y = 16.
Ipatiy [6.2K]

Answer:

12.5

Step-by-step explanation:

y varies inversely as x.

y = k/x

10 = k/20

200 = k

The constant proportion k is 200.

16 = 200/x

Cross multiply.

200 = 16x

200/16 = x

x = 12.5

Find the slope-intercept form of the equation of the line passing through the given points. (1, 1), (7, − 1 4 )
Serga [27]
Slope = (-14-1)/(7-1) = -15/6 

y = mx + c
y = -15/6 x + c
at (1,1)
1 =-15/6(1) + c
c = 1 + 15/6 = 21/6

y = -15/6 x + 21/6 or
6y = -15x + 21
